Embodiment 1
[0023] Example 1: Such as figure 1 Shown, a liquid density measurement method, especially for the measurement of liquid density in large containers.
[0024] A liquid density measurement method, used to measure the density of the liquid in the container in real time. The double flange level gauge is installed in the container, and the double flange level gauge is at the liquid level under the actual working pressure and temperature conditions. The pressure difference under the full scale and the pressure difference under the zero scale of the liquid level, and the density of the measured liquid is obtained by the following formula: P Full gap -P Zero difference =ρ liquid gΔh; where, P Full gap Is the differential pressure of the full-scale flange level gauge when the liquid level exceeds the pressure port on the double flange level gauge; P Zero difference Is the differential pressure of the flange liquid level gauge when the liquid level is lower than the lower pressure port ...
